Abstract
The present invention relates to a mine underground electric locomotive trolley wire connecting method. The trolley wires of the method of the present invention are connected with each other in a sectional power supply mode, a power supply device of each section is connected with the out end of the locomotive of the section, and a heavy rail wire of each section is connected with an air rail wire of the adjacent section in front of the travelling locomotive. The trolley wire connecting method is simple and easy to realize; underground apparatus of the trolley wires do not need to be changed and increased; the present invention can realize bidirectional power-off protection of the heavy rail and the air rail, which makes the heavy rail and the air rail not interfere with each other; when the heavy rail wire is broken, the air rail wire can operate as usual and vice versa. The present invention can effectively prevent human casualty accidents resulting from broken wires.
Description
The present invention relates to the bus connection method of mine underground electric locomotive trolley line.
At present, the air wire of mine underground electric locomotive all adopts the connection arrangement of sectional power supply, each power supply segmentation of air wire comprises the supply line of heavy rail linear load electric locomotive and the supply line of the unloaded electric locomotive of empty path, be associated with section switch between the heavy rail line of each segmentation and between the empty path, open under this section switch normal circumstances, play insulation bonded assembly effect between each segmentation, maintenance can closed section switch during electric supply installation, each segmentation is connected with the electric supply installation to this segmentation air wire power supply, there are many places to connect between the heavy rail line of per minute section and the empty path, electric supply installation to the heavy rail line and the power supply of empty path of this segmentation, has provided the bus connection method signal of prior art simultaneously in the accompanying drawing.Overcurrent and short circuited fender guard are arranged in the electric supply installation of each segmentation; but existing air wire does not have open circuit protection; when broken string appearred in locomotive operation the place ahead, electric locomotive still can move, and promptly broken string does not cut off the power supply yet; locomotive operation is to the broken string place; broken string and locomotive contact short circuit send strong electro spark, the burn driver; broken string can also be stabbed the driver, and this is a big hidden danger of safe operation.
Purpose of the present invention is for providing a kind of bus connection method of mine underground electric locomotive trolley line, and when making the air wire in locomotive operation the place ahead occur opening circuit, electric locomotive is because of the air wire automatic train stop that cuts off the power supply.
The present invention adopts following measure to realize: the bus connection method of mine underground electric locomotive trolley line, the described air wire of this method adopts the connection arrangement of sectional power supply, each power supply segmentation of air wire comprises heavy rail line and empty path, be associated with section switch between the heavy rail line of each segmentation and between the empty path, each segmentation is associated with the electric supply installation to this sectional power supply, the electric supply installation of each segmentation rolls end away from the locomotive of this segmentation and links to each other, the heavy rail line of each segmentation links to each other with the empty path of the adjacent sectional in locomotive operation the place ahead, this method is because electric supply installation is in the place ahead of locomotive operation all the time, when broken string appearred in locomotive the place ahead, electric locomotive was because of air wire outage automatic train stop.Use method of the present invention, under the situation that does not increase electric supply installation and other equipment, can realize the two-way breaking protection of heavy rail and empty rail, both do not disturb mutually, and broken string appears in the heavy rail line, and empty path can move as usual, and vice versa.
The bus connection method of electric vehicle overheading line of the present invention; it is improvement to the existing well underground electric locomotive trolley line; this method is simple; need not do any change and increase to down-hole air wire corresponding device; can realize the breaking protection of air wire; be that electric locomotive can be realized the place ahead broken string automatic train stop, the human casualty accident that can effectively prevent to break and cause.
Accompanying drawing 1 is the bus connection method signal of the air wire of prior art;
Accompanying drawing 2 is bus connection method signal of the present invention.
In conjunction with the accompanying drawings the present invention is further described as follows: the bus connection method of mine underground electric locomotive trolley line, the described air wire of this method adopts the connection arrangement of sectional power supply, each power supply segmentation of air wire comprises heavy rail line A and empty path B, be associated with section switch K between the heavy rail line of each segmentation and between the empty path, each segmentation is associated with the electric supply installation GDZ to this sectional power supply, electric locomotive all is a unidirectional operation on heavy rail and empty rail, the end that the locomotive of each power supply segmentation sails into is HD, the end that locomotive rolls away from is QD, the electric supply installation of each segmentation rolls end QD away from this segmentation locomotive and links to each other, the heavy rail line of each power supply segmentation links to each other with the empty path of the adjacent sectional in locomotive operation the place ahead, and the empty path of each power supply segmentation links to each other with the heavy rail line in locomotive operation the place ahead in other words.Use this bus connection method, the electric locomotive on heavy rail line or the empty path no matter, when it sails the power supply segmentation of broken string into, the electric locomotive parking of promptly cutting off the power supply.
Claims (1)
1, the bus connection method of mine underground electric locomotive trolley line, the described air wire of this method adopts the connection arrangement of sectional power supply, each power supply segmentation of air wire comprises heavy rail line and empty path, be associated with section switch between the heavy rail line of each segmentation and between the empty path, each segmentation is connected with the electric supply installation to this sectional power supply, it is characterized by: the electric supply installation of each segmentation rolls end away from the locomotive of this segmentation and links to each other, and the heavy rail line of each segmentation links to each other with the empty path of the adjacent sectional in locomotive operation the place ahead.
